It depends which Jepp package your company uses. TIBA is not an Australian animal- it is an global (ICAO) thingy so it appears with all the other ICAO stuff in the index. Hard to find..... NOT. Our company just uses the abreviated Australian pages amounting to just a dozen or less and TIBA is not in there. The procedure started life as an IATA initiative for places like Africa and Myanma and was called something like Inflight Broadcast Procedure.
